The magnetic flow on the manifold of oriented geodesics of a three dimensional space form
(Osaka University. Departments of Mathematics, 2013-09)
Let M be the three dimensional complete simply connected manifold of constant sectional curvature 0,10,1 or −1−1. Let L be the manifold of all (unparametrized) complete oriented geodesics of M, endowed with its canonical ...
Topological and Differential Invariants of Singularities of Contact Structure on a Three-Dimensional Manifold
(Cartagena de IndiasCampus Tecnológico, 2020-12)
A contact structure on a three-dimensional manifold is a two-dimensional distribution on this manifold which satisfies the condition of complete non-integrability. If the distribution fails to satisfy this condition at ...
Total torsion of curves in three-dimensional manifolds

A NOTE ON OPEN 3-MANIFOLDS SUPPORTING FOLIATIONS BY PLANES
(AMER MATHEMATICAL SOCPROVIDENCE, 2012)
We show that if N, an open connected n-manifold with finitely generated fundamental group, is C-2 foliated by closed planes, then pi(1)(N) is a free group. This implies that if pi(1)(N) has an abelian subgroup of rank ...
